I don't think we can unconditionally enable this. It is a big
behaviour change, and it is likely to break running systems. It has
affects on QoS, packet prioritisation, etc.
I think there needs to be a configuration knob. But unfortunately, i
don't know of a good place to put this knob. The switch CPU port is
not visible in any way.
